To understand how exactly these kinds of puzzles look like, let’s start the post with a very simple example. The method to solve the example will give better insight so as to how to approach these puzzles. Two smart players A and B are playing a coin game in which they can pick up 1, 2, 3 or 4 coins.

There are a few good ways to ace through the verbal section of the CAT or any exam like IIFT, XAT, SNAP etc. but the most entertaining one is to watch movies. Now after reading this, please don’t throw your books away and watch all the movies (and TV series of course) from your college collection neatly arranged alphabetically on your hard disk.

# Logical Reasoning Basics – Binary Logic – Liar, Truth Teller, and Alternator

May 24th, 2017 by

In a series of posts, we are going to cover the basics of some DI/LR topics. The first topic of discussion is Binary Logic. In a binary logic problem, we have people who either speak a true statement or a false statement. These people are divided into three categories: Truth-teller: This person will always speak the truth. All the statements made by this person are true. Liar: This person will always tell a lie. All statements made by this person are false. Alternator: This person always alternates between the truth and the lie. If first statement of this person is true, then se

# Words with Similar Meanings and Subtle Differences

A couple of days ago, 'The Republic' was unleashed on India and my opinion about Arnab as a journalist is quite similar to my opinion about Chetan Bhagat as a writer. But then, who am I to question or even criticize the role-model of the masses. During the last week, a role-model of the classes came under fire - Mr. Dr. Shashi Tharoor. There are allegations of wrongdoing about his involvement in the death of his wife, Sunanda Pushkar. Somehow, the very serious allegations were ignored and what caught the attention of social media in general, twitterati in specific, was Shashi's reactionary

# Words from Books and RC Passages

May 12th, 2017 by

In one of the earlier posts on this blog, we had discussed the important books for CAT preparation and how reading helps with tackling the verbal ability section. If you go through a lot of the reading comprehension passages asked in exams you will realize they are similar in tone to these books or newspaper articles and that is why reading helps. But just reading will not help. To really shave off time required in answering a question (especially in RCs) it is best if you know what the words mean eliminating the need to guess or take time to understand what the passage is talking about
